Figure 1) Map.

Daily 5km SST is shown for 2023-11-27, based on the latest remotely sensed data from NOAA Coral Reef Watch.

The ship icon represents thelocation of turtle release on July 10, 2023.

Black lines represent the 17°C isotherm. The Thermal Corridor area is outlined in white.



Figure 2) Average SST time series.

Weekly and long-term average sea surface temperatures at 4 longitudes in the eastern North Pacific (160W, 150W, 145W, 140W).

For each longitude, the darker lines with circles represent the weekly SST average during 2023.

To compare the current SST values during 2023 with the long-term average for the same time period, the lighter solid lines represent the long-term monthly SST averages between 1997-2022.

The black horizontal line at 17°C was used as a reference for optimal temperatures during turtle release.
